A cool looking plate armor skin that you can put into Armor Costume slot? I don't like any of my char's cloth armor, so... I would buy it... especially if it'll go into Account Item claim tab or.. if it'll continue being tradeable even after equipping it.
I would go for something like this, but I'm not sure it'd fly for a PvP game. The main argument you'll get is that it'll ruin the ability to visually identify your opponent by their armor. Which, shouldn't really be an issue since the weapons are REALLY obvious, but that's probably the main complaint you'd get.
Also, if they follow the trend of the current weapon skins, they'll be non-bankable/tradable and would be one use items for a single character.
Anyway, I'm just looking forward to more skins. Since the deadline for the current skins seems to be June 30th, hopefully they'll release a new batch of fun skins for me to mess around with, since the only one that would currently fit any of my characters is the giant sword and shield combo.
I can see it now: A mystic in 5-defense T11-looking plate armor running around the Island of Dawn.
